Direct current (DC) cardioversion is an effective means of restoring sinus rhythm in patients with atrial fibrillation or flutter; however, the existing literature contains conflicting evidence on which factors are useful predictors of success. In a study of 171 patients undergoing DC cardioversion, we found that duration of arrhythmia prior to DC cardioversion was the only significant predictor of both successful cardioversion and subsequent maintenance of sinus rhythm (P < 0.001). Rapid DC cardioversion after the onset of atrial fibrillation or flutter significantly increases the likelihood of a successful outcome in both the short-term and long-term.
直流电（DC）心脏复律是恢复心房颤动或扑动患者窦性心律的有效方法；然而，现有文献对于哪些因素是成功的有用预测指标存在相互矛盾的证据。在一项对171例接受DC心脏复律患者的研究中，我们发现DC心脏复律前心律失常的持续时间是心脏复律成功及随后窦性心律维持的唯一重要预测指标（P<0.001）。心房颤动或扑动发作后快速进行DC心脏复律显著增加了短期和长期成功治疗的可能性。
